CWNP Updated CWDP-305 Exam Questions and Answers by veer

Comprehensive and Detailed Explanation:

iPerf is a widely used network testing tool that measures the maximum achievable bandwidth on IP networks. In the context of wireless site surveys and validation, iPerf is utilized to perform throughput testing, providing insights into the data transfer rates between devices. This information is vital for assessing the performance of the wireless network and ensuring it meets the required specifications.

In the 2.4 GHz band, 40 MHz channels are formed by bonding two adjacent 20 MHz channels. The primary channel is the one the client uses to initiate communication, and the secondary channel is either above (+1) or below (-1) the primary.

For channel 4 as primary with a +1 secondary offset:

Primary channel: 4 (2.427 GHz)

Secondary channel: 5 (2.432 GHz)

This configuration stays within the allowed channels 1-11.

Comprehensive and Detailed Explanation:

When analyzing a customer's existing infrastructure, obtaining read-only access to certain systems is crucial for gathering information without risking unintended changes. The systems include:

B. RADIUS:Accessing RADIUS servers allows you to review authentication logs and configurations, helping to understand how network access is managed.

C. Switches:Reviewing switch configurations and logs provides insights into network topology, VLAN assignments, and potential bottlenecks.

D. Active Directory:Access to Active Directory helps in understanding user authentication mechanisms, group policies, and organizational units, which are essential for designing access controls.

E. Routers:Examining router configurations and routing tables aids in understanding traffic flow, subnetting, and inter-network connectivity.

A. Clients:Direct access to client devices is generally unnecessary and can pose privacy concerns. Information about client behavior can often be gathered through network monitoring tools.

The IEEE 802.11-2016 standard specifies two methods for Fast BSS Transition (FT) to facilitate fast and secure roaming:mrn-cciew

Over-the-Air (OTA):The client communicates directly with the target AP to perform the authentication exchange during roaming.

Over-the-Distribution System (Over-the-DS):The client communicates with the current AP, which then communicates with the target AP over the distribution system to perform the authentication exchange.

These methods are designed to reduce the time required for re-authentication during roaming, ensuring minimal disruption to ongoing sessions.

The CWDP-305 Official Study and Reference Guide states:

"802.11r defines two methods for fast BSS transition: Over-the-Air and Over-the-DS, both aimed at reducing latency during client roaming."
